Tapchanger Type ABS, 11 kV

On Load Gears offers an On Load Tapchanger, ABS III 200 17 170, suitable for applications at all locations of 11 kV, three phase, star or delta connected transformers. It is a linear gear requiring a potentiometric tapping arrangement, with a wander lead. The tapchanger has a maximum of 17 positions, so that it can be applied to a winding of 16 steps, to give 17 different voltages. The functions of the tap selector and diverter switch are combined in a selector switch. The selector switch and its integrally mounted stored energy type driving mechanism are housed in a sheet tank, with a flange suitable for mounting on a port on the transformer tank. Leads can be brought out of the transformer through a port flange mounted, oil tight, terminal barrier board, which is part of the tapchanger supply. The tapchanger must be connected to a conservator, through an oil surge protective relay. The oil surge protective relay forms parts of tapchanger supply, but the conservator and transformer oil are not in the scope of supply. The tapchanger must be filled with oil by the transformer manufacturer. The company also offers Porcelain Clad Outdoor VCB.
